Hi there,
in your Customizer > Additional CSS you have this CSS rule which is adding those arrows:
.entry-content ul li:before {
content: "\279C";
position: absolute;
left: -1.5em;
color: #689931;
}
So that applies to every list in your post content which applies to those social icons.
Options:
a. You could simply copy the social buttons you have in your footer block element, as those are GenerateBlocks buttons they won’t get that style.
b. change the above CSS to this:
.entry-content ul:not(.std-list) li:before {
content: "\279C";
position: absolute;
left: -1.5em;
color: #689931;
}
Then select the Social Links Block ie. the wrapper around the icons not the individual icons, and in Advanced > Additional CSS Classes add: std-list
